1. On occassion, the Hedge Maze Guardian spawned 5 spriggans on the second spriggan phase. It might have been because I pushed the health lower past the threshold? Usually it spawns 3 on the second phase, and in the group dungeon too, so I think this might be unintentional.
2. Hedge Maze Guardian's animations sometimes get desynced, after Thorn Toss, likely due to moving while trying to cast Thorn Toss. The cone telegraph remains attached while the boss is not actually casting, subsequent Crushing Limbs were not animated, and I died, or would have died without addons. You can see in this video the recasting going wild (center screen from CrutchAlerts), and then snapping into the Crushing Limbs animation with no wind-up: https://youtu.be/HZb6sRM4EX4
3. Vykosa's Rending Slash animation is consistently desynced from the actual damage. She's still on the ground when the damage hits, and only after does she jump up. The damage lands ~700ms before the animation appears to. You can see the cast timer for Rending Slash (center screen) which is correct, and the damage taken blocked from the LUI combat text as well as base game, but the animation and sound do not line up: https://youtu.be/aeQGz5ubVKs

Some grammar nitpicking on the MM selection tooltip:
1. Abilities are countable, so it should say "have fewer abilities"
2. For consistency with the 0MM part, the 2MM and 3MM should use "health pools" in the plural, i.e. "have larger health pools"
3. The 2MM's first point is worded weirdly with an "and" in the middle of the list. It should probably say "Monsters deal dangerous amounts of damage, have larger health pools, can use deadlier abilities, and appear in greater numbers"
